Answer:
The Reynolds numbers for flow in the fire hose.
Explanation:
Given that,
Diameter = 6.40 cm
Rate of flow = 40.0 L/s
Pressure 
We need to calculate the Reynolds numbers for flow in the fire hose
Using formula of rate of flow


Where, Q = rate of flow
A = area of cross section
Put the value into the formula


We need to calculate the Reynolds number
Using formula of the Reynolds number

Where,
=viscosity of fluid
=density of fluid
Put the value into the formula


Hence, The Reynolds numbers for flow in the fire hose.
